Estimating Gradient

For a line that isn't straight, we can estimate roughly what the gradient is.

Gradient at a point

  • To estimate the gradient at a point draw a tangent to the curve at that point.
  • Work out the gradient of the tangent.
  • Remember that gradient = change in y ÷ change in x.
Illustrative background for Gradient = change in y ÷ change in xIllustrative background for Gradient = change in y ÷ change in x ?? "content

Gradient = change in y ÷ change in x

  • To estimate the gradient use gradient = change in y ÷ change in x.
  • But remember it is only an estimate because the curve isn’t straight.
